Numerous experiments have demonstrated the possibility of attitude polarization. For instance, Lord, Ross & Lepper (1979) partitioned subjects into two groups, according to whether or not they believed the death penalty had a deterrent effect, and presented them with a set of studies on the...

In many areas of economics there is a growing interest in how expertise and preferences drive individual and group decision making under uncertainty. Increasingly, we wish to estimate such models to quantify which of these drive decision making. In this paper we propose a new channel through...

A large theoretical literature assumes that experts di ffer in terms of preferences and the distribution of their private signals, but the empirical literature to date has not separately identi ed them. This paper proposes a novel way of doing so by relating the probability a member chooses a...
